ELECTRIC-LIGHT SUPPORT.

Specification of Letters Patent.

Patented July 3, 1917.

Application filed May 23, 1916. Serial No. 99,408. I

To all whom it may concern Be it known that I, Giu'snern A. CnN'ro-LELLA, a citizen of the United States, residing at Clinton, in thecounty of Oneida and State of New York, have invented new and usefulImprovements in Electric-Light Supports, of which the following is aspecification.

This invention relates to an electric light support, primarily designedfor holding and supporting an incandescent electric lamp with thecomponent parts of the lamp fixture upon the arm of a sewing machine, insuch manner as to adapt the light from the lamp to be directed upon thework to afford greater ease and convenience in sewin when the machine isused at night or in a ark place.

The object of thejnvention, is to provide a simple, convenient andinexpensive form ,of light fixture which maybe readily clamped to thearm of the machine and which permits adjustment of the lamp to differentangles as required to direct the rays of light in the desired direction.

The invention consists of the features of construction, combination andarrangement of parts hereinafter fully described and claimed, referencebeinghadto the accompanying drawing in which Figure 1 is a frontelevation showing the application of the invention to the arm of asewing machine, andshowing in full and dotted lines some positions towhich the lamp may be adjusted.

Fig. 2 is a side elevation of the device. Fig. 3 is a top plan view ofthe same. Figs. 4, and 5 are longitudinal sections through portions ofthe lamp fixture. Fig. 6 1s a view showing a modification. In carryingmy invention into practice,-I rovide a band or attaching member 1 whichis adapted to embrace the arm of a sewing .machine and 15 provided withflanged ends 2 perforated for the passage of a bolt 3 provided with asecuring nut 4, whereby the band when applied may be firmly fastened in,position on the machine arm. The band serves as the main support for theelectric lamp 5 which may be of a type comprising a globe 6, socket 7and shade 8 partially receiving and. inclosing one side of said globe,

and which may serve also as a reflector.

The socket 7 receives a threaded end 9 of a tubular connecting member10, which is adapted to be securcdtherein against d1sat its opposite endwith a pair placement by the usual set screw 11 upon the socket, thesaid connector 10 being provided apertured cars 12. a

The ears 12 of the connector 10 receive between them an car 13 formedupon a second tubular connector 14-: having at, its up posite end anapertured ear 15 arranged at right angles to the cars 12 and 13, whichcars 12 and 13 are perforated for" the pas sage of a bolt 16 providedwith a clamping nut 16, whereby the connecting members 10 and 14: arepivotally united and adapted for relative adjustment for articulatingmotion with greater or less freedom.

In practice, certain of the connecting of spaced members are preferablymade of tubing having a greater or less degree of spring action orresiliency, so that the binding motion of the pivotally connected earson each other may be varied and regulated by the connecting bolts, thusenabling the joined parts to be disposed at different relativeangles andheld connected in a positive and certain manner without liability ofrelative dis-' placement. i

The second connecting member 14 has its car 15 arranged between theperforated cars 17 at one end of a tubular supporting arm 18, the saidears 15 and 17 being, disposed in a plane at right angles to the ears 12andv 13 and being pivotally connected by a bolt 19- having'a securingand adjusting nut 20, whereby the second connecting member is adjustablypivoted to the free end of the arm 18.

The opposite end of the arm 18 is provided with perforated cars 21disposed in a plane at right angles to the cars 15 and 17 and whichengage flattened surfaces 22. at one end of a tubular connector 23,having a shank 23' which is perforated for the passage of a bolt 24provided with a securing and adj u'stin g nut 24', whereby the members'18 and 23 are pivotally coupled forr'notion curing and clamping nut 28,whereby the" j be swiveled together, to permit rotative motion of thearm 18 through the connector 23, on the' band 1, as will be readilyunderstood,

while permitting said'parts to be drawn to-.

gether and fixed in clamping engagement with each other against motionafter adjustment, as will be readily understood.

In practice, the conducting cord or wire 31 leads through the arm 18 andconnectors 14 and 10 to the socket 7 thus providing for the inclosure ofthe cord for supplying current to the lamp from a suitable source insuch a manner as to prevent the cord from becoming kinked or tangled,while permitting it to bend or flex with the jointed elements of thesupporting bracket or arm in disposing the lamp in difi'erent fworkingpositions. I v

It will be obvious from the foregoing de scription that when the band 1is ap' lied to the arm ofa sewing machine, as in icated, the lamp 5 willbe supported so that it may be bent upon the joints or pivots 16, 19, 24and 29, so as to be disposed in different positions above, in advance orin rear 'of the machine arm and in difl'erent positions laterally andlon gitudinall of said arm, so as to throw light at di erent angles orfrom different positions toward-the work, while the eyes of the operatorare protected by the shield 8, from the direct glare of the rays, thusenabling the workto be inspected at all times and clearl viewed, irresctive of other natural lig t-conditions. he lamp may also be disposed inan out-of-the-way position when not in use, or so as not to interferewith the work at times when the use of an artificial light is notneeded.

In Fig. 6 I have shown a modification in the construction ofthe swivelconnection between the arm 18 and the connector 23. In

- this construction the split ring lis provided with a tubular portion1" receiving a stem 22 which is fitted to turn or rotate therein.

-.against endwise movement while permitted to tu rn or rotate in saidtube. -The stem is provided with an apertured ear 22 for connection withthe cars 21 through the medium of the bolt 24.

If desired, instead of employing bolts with nuts .to pivotally connectthe jointed sections, said sections may be unitedby headed pins orrivets arrangedto permit pivotal motion thereof, while maintaining thepivoted parts in frictional engagement to hold them in any position ofadjustment.

I claim':

1. An electric light support comprising a lamp, a carrying membertherefor, an attaching member, and a series of jointed arms connectingsaid carryin and attaching members, said arms inc uding a centraltubular arm and intermediate arms, one of said intermediate arms beingjointed in planes at right angles to each other to the 'lamp carryingarms and central tubular arm and the other of said intermediate armsbeing jointed to the opposite end of the central tubular arm to swing ina plane at right anglesto the pivotal connection of the firstnamedintermediate arm of the central tubular arm, said second-namedintermediate arm being swiveled to the attaching member.

2. An electric light support for sewing machines comprising a lamp, aclamping member having a stationary I head thereon and jointedsupporting arms- Iconnecting said lamp and clamping member, one of saidsupporting arms having a socket therein and a retaining flange partiallyclosing the entranceto saidsocket, said supportingv arm and flange beingsplit for the greater portionof the length on the socket forminggripping jaws for swiveling connection to said head on clamping member.

In testimony whereof I aflix my signature.
